How Much Longer Will We Use Desktop PCs?

Is the Desktop PC Dead?

A Look At How Even With Falling Sales, Desktops Are Still Relevant

Mark Kyrnin | March 8, 2016

It has been clear for some time now that in the mind of consumers, desktop computers just are not popular. The ability to take a computer with you on trips, to and from work or school or just taking up less space in a household have made laptop sales larger than desktops for some time. With the rise in tablets the past couple years, now there is even talk about falling laptop sales as well. So what exactly are the reasons that desktop computer sales in particular have fallen so dramatically?
Most people will likely point to the portability of laptops as being the primary reason that desktop sales are falling but I would argue that it is the price and performance gaps that are the prime culprits.
